Brazil is one of the few countries in the world with an equatorial forest (together with Congo, in Africa), which is limited to the equatorial climate. Such climate is predominantly seen over the Amazon Forest region, where average temperatures vary from 24 to 26°C.

The tropical climate prevails over the Central Plateau region, as well as over other northeast and southeast Brazilian regions. This climate is characterized by two distinct annual hot seasons, with average temperatures over 20°C.

At higher regions, limited by the Atlantic Plateau at southeast, and even in regions at south of Mato Grosso do Sul and north of Paraná, the predominant climate is the so-called altitude tropical climate. Average temperatures range from 18 to 22°C.

The so-called Atlantic tropical climate prevails over almost the entire Brazilian seacoast, extending from Rio Grande do Norte to Rio Grande do Sul. Such climate records average annual temperatures ranging from 18 to 26°C.

The semi-arid climate covers the territory corresponding to the northeastern midland, from the São Francisco River valley to the north of the state of Minas Gerais. Annual average temperatures are among Brazil's higher ones, namely about 27°C.

The coldest region corresponds to the territorial area located below the Capricorn Tropic, which includes the southern states, with the exception of the northern Paraná.

This region's sub-tropical climate records average temperatures below 20°C, where winter times are the country's rigorous ones, especially in those areas of higher altitudes, where blizzards are likely to occur.
